1.3 There are nine specifications covering the following areas of event planning: destination selection, accommodations, food and beverage, audio visual, onsite offices, communication and marketing materials, transportation, exhibits, and venues. Within each specification are eight categories’ criteria: staff management policy, communications, waste management, energy, air quality, water, procurement, and community partners. Each category is further split into four progressive levels of achievement. Information within each specification is divided as follows: Main BodyScope, Referenced Documents, Terminology, Planner Requirements for Level 1, Supplier Requirements for Level 1, and Keywords; AnnexesPlanner Requirements for Levels 2 – 4 and Supplier Requirements for Levels 2 – 4.

1.4 All areas of performance under this specification may not be relevant for each event or for each facility or provider of event services. In some cases, an event planner would use this specification in conjunction with other specifications (for example, Specifications , ) or this specification may be used individually. In other words, elements of an event may be separated and considered solely or added together and considered as a unit (for example, venues used individually versus transportation, accommodations, and destination selection used in conjunction).

1.5 If higher levels are achieved in some sections, the event can only be considered environmentally sustainable at the lowest level achieved.

1.6 The use of levels within this specification recognizes the path to environmentally sustainable events is a multi-stage effort. The idea behind the levels is to provide a coherent baseline for measuring environmental performance, to be flexible enough to adapt to the needs of more advanced planners and to establish a performance path that encourages further environmental performance improvement. In addition, the evolution of products and services to support events is expected, allowing additional advancements and underscoring the dynamic nature of environmental sustainability. This specification primarily focuses on environmental sustainability, while some aspects of economic and social sustainability are included recognizing the complete path toward overall sustainability.

1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
